How to make appointments visible in the popup callendar of RadScheduler

Highlight the days that have at least one appointment in the pop-up calendar.

DESCRIPTION

The user cannot easily see the appointments that are not included in the currently selected view.
Instead of going through the Scheduler to find appointments, an easier way is to have the dates which have appointments highlighted in the popup RadCalendar. Here's how this is achieved:

Subscribe to the OnPreRender event of the RadScheduler.

Find the RadCalendar control located in the RadScheduler.

In the OnPreRender handler, access and loop through all visible appointments of RadScheduler. Get the Start of each appointment, format it's style by a CssClass and add it in the SpecialDaysCollection of the RadCalendar.
